- JOHN C. IE'ELTON, OF SAN FRANCISCO, CALIFORNIA. 1

' To all whom it may concern." 1

Be itknown that I, JOHN C. PEL'roN, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have inventednew and useful Improvements in CompactingApparatus, of which the following is a specification.

My invention relates more particularly to a power driven apparatusadapted to settle into a compact mass, concrete in mold forms, and othermaterials in containers.

In the manufacture of articles from concrete it has been the practice toimpart to the mold forms a jarring or oscillating movement to settle themass in order to produce an extremely dense and solid article or objectfree from sand, air cavities, or other imperfections. This motion hasgenerally been accomplished by mechanical means and applied to aplatform or other support mounted on springs or other resilientinstrumentalities which do not impart a uniform agitating movement tothe support, resulting in some cases in imperfect prod ucts.

By the employment of a fluid supported platform or support, andimparting a constant jarring or agitating movement thereto, I am enabledto produce an extremely uniform motion to the mold forms, or containers,resulting in the production of articles of concrete or objects of aplastic nature free from imperfections.

It is an object of my invention to provide able support will beuniformly and evenly agitated throughout its entire area.

A further object of my invention is to provide an apparatus, whereby alarge variety of agitating movements and combinations of the same may beimparted thereto to suit the type of materials that are being compacted.

I accomplish the above objects by means of the apparatus hereindescribed and illustrated in the accompanying drawings, in which:

Figure 1 is a sectional View of aform of my improved apparatus.

Fig. 2 is a sectional view through a modified form of apparatus.

In the drawin s I have illustrated an app fetus in whic' the mainfeatures of my invention are represented, the farms differ ooMrAo'rnvGAPPARATUS.

ing only in the means of communicating motion to the support. Otherforms of pro' ducing a variety ofmotions may be'employed, but I considerthat the important feature of my invention resides in the resilient andelastic support for the forms and containers. Referring to Figs. 1 and 2the apparatus preferably consists of atank 5,0f any desired slze andconfiguration, preferably constructed from wood. This tank is nearlyfilled with water 6 and supported by the same is a chambered floatingplatform or support 7 of substantially the same configuration as thetank. Mounted on one side of tank 5 is a bracket 8, to which is rigidlysecured a motor 9 of any approved type. The frame of motor 9 is providedwith a bearing arm 10 which projects inwardly and over the top ofsupport 7, and has a shaft 11 carrying a wheel 12 provided with aplurality of teeth. The shaft of motor 9 carries a driving pulley 13,which is belted to a driven pulley 14 secured to one end of shaft 11 torotate the toothed wheel.' Secured to the face of support 7 and directlybeneath wheel 12 is a semi-spherical metallic contacting member 15against which the teeth of wheel 12 contacts during the operation of theapparatus.

The operation of my apparatus will be instantly comprehended from theabove description, the motion which is transmitted to the support beingextremely even and uniform, and ranging from a delicate to a mostviolent one.

In Fig. 2 I have illustrated another form of agitating means consistingof substan tially the same character of apparatus as in the firstdescribed form, the motor imparting a reciprocatory motion by means of acrank 16 secured to the motor shaft and a rod 17 pivotally secured tothe upper face of the support.

Various other mechanisms for imparting a variety of motions to thesupport may be utilized, such as agitating the fluid in the tank bymechanical or pneumatic means, but I consider, as heretofore noted, thatmy invention primarily resides in a floating suport.

p In the first figure of the drawing, I have illustrated a concretebrick mold form 20 on the su porting platform 7, the form being divic edby partitions into a lurality of compartments. any steer suit/a l'eforms may be used in compacting various other materials With equallyeflicient results.

What I claim is:

1. In an apparatus of the class described, a fluid supported mold form,and means for impartingmotion thereto.

2. In an apparatus of the class described, a fluid supported mold form,and means for imparting motion to said form to move the same in aplurality of planes.

3. In an apparatus of the class described, a fluid tank, a floatingmember mounted in said tank, a mold form mounted on said member, andmeans to impart movement to said member.

4. In an apparatus of the class described, a fluid tank, a chamberedstructure mounted in said tank and supported by the fluid therein, saidstructure being free to move in any direction, a mold form mounted onsaid chambered structure and means to impart movement to said chamberedstructure.

In Witness that I claim the foregoing I have hereunto subscribed my namethis 15th day of March, 1918.

JOHN C. PELTON.
